The embodiment of the invention shown in the drawings comprises a drum D consisting of a cylindrical shell arranged with heads 8, 9 at the opposite ends having axially projecting hollow trunnions 10, 11 whereby the drum is revolubly supported in bearings 12 mounted upon a supporting foundation' 13. The trunnions are of relatively large diameter to provide a large bearing surface and have mounted therein annular members 14, 15 to reduce the size of the openings through the drum trunnions and thereby maintain the capacity of the drum, the opening through the reducer 14 constituting the charging opening of the drum and the'opening in the reducer 15 the delivery opening.

The cylinder is arranged with a wear resisting lining consisting of annular axially arranged sections 16 of suitable material, such as manganese steel, said sections being retained against displacement in the shell by plugs 17 engaging in recessed portions of the lining sections and secured to the shell by bolts as shown. The drum is revolved from a suitable source of power by means of a gear 18 arranged concentric of and iixed to the drum. The material is fed to the drum by means of a hopper 19 fixed to the charg- 1ng trunnion to revolve with the drum, said hopper having an axial inlet opening 20 Vand an outlet communicating with a sleeve 20 engaging in the opening in the trunnion reducer with a spirally and angularly arranged partition 21 in said hopper operating through the revolving of the drum tocarry material in the'ho per from below the axis .of the'h'opper to a -ovejthe axis and in such latter' positionjjdirectfthe I iatrial linto the sleeve :inj the opening "1in the '-trun'nion refdncerhisaidcpening having "a ,spiral rib' or screw 2 1' there in 'tofA feed the material `through 'the sleeve 20,i 11, t 0' the drum;

fllhefdruinisjseparatedlinto axially arrangedch-ambers' comprising a primary disintegrating chamber A, a collecting chamber B to receive disintegrated material from the primary disintegrating chamber, a secondary disintegrating chamber C,- in which to receive and reduce material to a finer degree which material has been lsubjectedtto primary disintegrating action in the primary disintegrating chamber, and a secondary collecting chamber E to receive disintegrated material from the secondary disintegrating The disintegrating chambers A between the primary disintegrating chamber and said collecting chamber through which to deliver disintegrated material fromthe primary disintegrating chamber A to the collecting chamber B. The openings in this wall 23' have greater length t an widthand the walls thereof diverge from the side facing the disintegrating chamber A to'thc opposite side, said openings being arranged in concentric circular rows with the openings of the different rows inclining in opposite directions as shown.- By this arrangement of the wall of the openings there is no possibility of the material packing in 'and clogging the np'enings.l The screen wall 23 consists of segments and the walls 23, 22 of the collecting chamber are secured together by bolts 25 and rivets 26, the walls being maintained in spaced relation by radial ribs 27 arranged preferably in al with the wall or plate 22, said ribs belng located so that they willengage the segments of wall 23 at the meetingvedges, as clearly shown in Figure 4. These ribs begin at a point out- Ward from the axis of the plate 22 and terminate within the periphery thereof to provide annular passagesbetween 'the inner and outer ends of said ribs with which the radial passages formed by the ribs communicate. The outer peripheral portion of the segments constitutin wall 23 and the plate or wall 22 have laters. y extending Hange's 28 and 29 which are adapted to meet when the wallsranged# The screening chamber is separated byan annular screen partition 34 into concentric compartments G and H. The compartment G is connected to the collecting chamber B to receive material on the screen 34 through openings 35 arranged in the flanges 28, 29 of walls 23 and 22, and that portion of the drum containing the collecting chamber, there being four of these openings in the present instance equidistantly spaced apart around the periphery of the drum. The material flows through said openings 35 from the collecting chamber onto the screen partition 34 in t-he screening chamber when said openings are below the axis of the drum. The outer wall of the screening chamber is constructed of semicircular plates having the ends flanged laterally whereby they are secured together by rivets or bolts, as shown at 30, and end or4 side walls 31 consisting of semi-circular plates to engage within the outer wall and flanged laterally whereby they are secured to the wall by rivets or bolts, as shown at 32, and reinforced by angle iron 33, the screen being secured to the drum by angle iron 33 riveted or bolted to the side walls31 and the drum.

The. material received in the compartment G on the screen 34 passes through the meshes of the screen into the compartment H and any material which is too coarse to pass through the meshes of the screen is returned to the primary disintegrating chamber A for regrinding. For this purpose the compartment G of the screening chamber is arranged with openings 36, there being two of these outlet openings arranged in the wall of the drum and at the end of the screening chamber opposite the inlet openings 35. The material through the action of centrifugal force as the drum is revolved will tend to be thrown outward against the screen wall 34 and the material is directed toward the outlet openings 36 by a spirally arranged rib 37 in the form of angle iron secured to the screen wall within the chamber G. The material is directedy by said rib to vanes 38, which may be in the nature of pockets, which .will pick up the material from below the axis of the drum and lift the material toward the'axis of the drum, and as said vanes approach the axis of the drum they are so constructed that they will direct ordelect the.

material through the openin s 36,'and as the material passes through sai openings they will Aengage deectors 38. within the primary disintegrating chamber, said dellectors 38 also serving as a means toprevent material from the primary disintegrating chamber entering the screening chamber through the. openings 36.

The screened material which is passed through the screen 34 to the outer compartment H of the screening'chamber F is delivered into the secondary disintegrating chamber C to be reduced to a finer degree by the action of disintegrating elements in said chamber, in the form of steel balls or the like. F or this purpose there is arranged ,in the collecting chamber B a pesage-way 39 having inlets 40 arranged diametrically opposite through the flanges 28, 29 of the wall 23, '22 of the collecting chamber, said passage'having an outlet 41 arranged axially in the wall 22 and leading into the secondary disintegrating chamber. The passage 39 is formed by parallelly and spaced apart ribs 42 extending radially outward from the out-5 let opening 41 to the periphery of the plate 22. To direct material through the outlet opening 41 a dellector is arranged in the passage intermediate the ends thereof, said deiector comprising a disk 43 (Figures 5 and 7) secured in position by the bolts 25 which serve to connect the walls of the collecting chamber, and said disk being arranged with opposite peripheral walls 44 to constitute a continuation of the passage Walls 32 and having a portion 45 of V-shape in cross section the apex of the oppositev inclined walls of which are arrangedaxially of the opening 41 and have semi-circular portions 46 extending laterally from the parallel walls 44 to engage a corresponding seat 447 formed about the outlet opening 41 and to engage the inner ends of the radial reinforcpassage 39 are connected to the' compartment H of thescreening chamber by means'of tubular `members 48 of the same cross sectional shape as the passage extending through the compartment G of the screening chamber. Material from the compartment H of the screening chamber is delivered to the passage 39 through the tubular member 48 spaced apart approximately ninety degrees around the perlphery of the drum whereby as said outlets 48 from the compartment H are below the axis of rotation of the drum material from the compartment H will enter said members and is lifted upward with the movement of the drum and as they are positioned above the axis of rotation of the drum the material will pass through said connecting members into passageway 39 and through the latter into the secondary disintegrating chamber C. To cause the material from the compartment H to enter the passage 39 deflectors are arranged in compartment vH, which are in the nature of artitions 49 extending from the outer wall o the compartment to the screen partition S and spirally arranged to extend from the side wall 31 at the side of the screen chambers opposite said openings 48 and in a direction toward said openings, the portion of the screen partitions 34 adjacent the outlets between .said defiectors and the side wall 3l being preferably arranged with an unperforated material to prevent re-entering of the material through the screen partition into the compartment G from compartment H.

The disintegrated material from the secondary disintegrating chamber C is delivered through a transverse screen partition 49 into the chamber E. This partition has openings therethrough of a structure and arrangement similar to the openings 24 through the partition 23 and has an opening centrally thereof and axially of the drinn leading to the delivery opening through the trunnion reducer 15, the Wall of said opening flaring outward from the drum and being of less diameter than the reducer opening to provide an annular space 5() between said partition and the reducer opening to constitute the outlet for the chamber E. The partition 49 is connected to and carried by the drum head 9 and trunnion reducer by bolts 51 and maintained in spaced relation to said head by spacers 52, said spacers being arranged as scoops or buckets to pick up the material in the chamber E from below the axis of the drum and lift it through the revolving of the drum to above the axis of the drum and direct it to the space between the partition 49 and the reducer l5 to deliver the material therethrough.

The material is delivered from the chamber E through the trunnion reducer 15 onto a cylindrical screen 53 connected to said trunnion reducer to extend co-axially thereof, the material passing through said screen being collected in a hopper arranged below the screen from which it is delivered to a suitable receiver, while any coarse particles of material are delivered from the outer end of the screen into a suitable receiver therefor.

A tubular member 54 is connected to the trunnion reducer 15 as by bolts passing through perforated lugs extending laterally from said member and inwardly from said reducer, as shown at 55,- said member being of a diameter less than the internal diameter of the trunnion reducer and substantially of the same diameter as the flaring wall of the central opening of the partition 49 and constituting an extension of said wall to extend substantially for the full length of the screen 53. This tubular member 54 is for the purpose of feeding the grinding elements to the secondary disintegrating chamber C, and to facilitate the feeding of said rinding elements there is arranged on the mner peripheral wall a spiral rib or screw 56 which operates Ito propel the grinding elements through said member by the revolvingof the drum. The material to be disintegrated together with liquid, such as water, is delivered to the primary disintegrating chamber A through the charging opening leading to said chamber.

While there has been described and illustrated one embodiment of the invention, it is obvious that various changes and modifications may be made in the form and structure of the apparatus, and that portions of the invention may be used Without others, and come within the scope of the invention.
